Physics Made Easy

Hi Physics Lovers !

Two new videos coming up soon!
Both will be related to escape velocity:

In the first one, that hopefully should be out tomorrow, you will learn how to calculate the size that would have any object if it were a black hole. The example that I took in this video is the Earth.
Do you have an idea of how large the Earth would be if, suddenly, it collapsed into a black hole? The answer is mesmerizing! Watch the video to find out. And even better, you will learn how to calculate that yourself!

The second one is more of a full lecture regarding the concept of escape velocity. In order for you to really understand what it is, we will first review the energetics of a system of two masses. By understanding the relationship between kinetic energy and potential energy of such a system, you will be able to spot what an object needs to definitely escape from a gravitational field.

To do so, we will take the example of a rocket trying to leave a planet. Finding conditions on the energies of such a system will allow us to derive a formula for escape velocity. We will then use this formula to determine the size of the Earth if it were a black hole. So, you see, the first video is kind of a teaser to the full lesson.

Moreover, for students that are actually studying this subject at school, I will add some slides at the very end of the second video with training exercises. Like this, you can be a master of the topic in your physics class!

In this video, there are many animations that I am currently building. With the limited tools I have at my disposure, it is quite head-scratching to make these animations accurate in regards to the physical reality. But I’m getting there! I expect this video to be out in a week or so.

I hope you enjoy these videos, and wish you the best!

Ciao!

Edouard


PS - And of course, the little self-promotion section 😊:

Encourage me by listening to the Physics Made Easy music album here: edouardreny.bandcamp.com/album/physics-made-easy-t….

I am not too fond of Patreon stuff, I prefer giving something concrete in exchange for any financial support, so if you like the music, please download the album!

Unlock the Mysteries of the Cosmos: A Groundbreaking Theory That Changes Everything What if everything you've been taught about the universe is not just incomplete, but potentially a great misconception?.I present to you the Grand Unified Gravitational Theory (GUGT), a revolutionary perspective that will challenge your understanding of reality itself. This theory goes beyond traditional astrophysics, addressing some of the deepest mysteries that have puzzled humanity for centuries. In this document, I share a new framework for understanding the universe—one that transcends conventional science and opens the door to infinite possibilities. This isn't just another theory; it’s an invitation to explore the very nature of space, time, and existence itself. Here’s why you should read this: 1.The Truth About Black Holes: What really lies inside a black hole? I reveal the hidden processes that shape the universe, challenging our current understanding of gravity and time. You’ll discover how black holes are far more than cosmic vacuums—they are the drivers behind cosmic evolution. 2.The Illusion of Dark Matter and Dark Energy: What if dark matter and dark energy, the most mysterious forces in the universe, were nothing more than cosmic illusions? Through the lens of GUGT, I explain how these phenomena are misinterpreted effects of black hole gravity, forever altering how we perceive the universe. 3.A New Origin Story for the Universe: Forget everything you thought you knew about the Big Bang. This theory offers an entirely new explanation for the universe’s birth—a cyclical, ongoing process of creation, destruction, and rebirth. It presents a universe that is born, dies, and is reborn in infinite cycles. 4.The Ultimate Fate of the Universe: What happens when the universe reaches its end? How will life survive the final collapse? I present a path forward, detailing how civilizations might escape the collapsing universe and journey into the multiverse—an existence that transcends the boundaries of space and time. 5.The Multiverse: What lies beyond our universe? I delve into the mind-bending concept of the multiverse, where countless universes cycle through existence, offering endless possibilities for intelligent life. Whether you're a curious reader, a student of physics, or an enthusiast of the cosmos, my Grand Unified Gravitational Theory will captivate your imagination and expand your understanding of the universe. Don’t miss out on this transformative journey.

The cosmos is waiting for you to discover its deepest truths.
